WINDOW.

SPECIFICATION forming part of Letters Patent No. 714,776, dated Decemberf, 1902.

Application filed May '34, 1901.

To a/ZZ whom it mctyrconjoern:

Be it known that I, `PERRYBROWN, a citizen of the United "States, residing at AWilmington, in the county of Newcastle, State of Delaware, have invented a certain new and usefullmprovement in Windows,`of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in windows, more particularly of that class in which aspring-actuated strip is employed to hold the sashes in place, although it will be manifest that parts of my invention are applicable to other styles of Windows.

One of my objects is to provide a window in whichV the sashes may be easily removed without removing any of the strips on the outside of the frame, as is usually the case with the Windows commonly used;

A further object is todevise means by which the sashes may be held in any positionl without the use of cords, pulleys, and weights,`

and which means may be so arranged as to be regulated in order that the sashes may be moved with the greatest ease when occasion requires it.

With these and other incidental objects in view my invention consists in the peculiar arrangement, construction, and combinations of parts hereinafter set forth and then deiinitely claimed.

In the accompanying drawings, Figure 1 is a side elevation of a window with my invention applied thereto, but with parts broken away to show theconstruction of the novel parts. Fig. 2 is a cross-section through the line @c of Fig. l. Fig. 3 is an enlarged section showing the mechanism for releasing or tightening the closing-strip. Fig. 4 is a detail section, on a larger scale, showingthe removable stripsby means of which the sashes may be removed. 5 is a perspective secings by numerals, `1 indicates the Windowframe,havingthe usual upperandlower sashes serial' No. 61,760. `(no model.)

2 and 3 sliding in recesses therein. This frame 1 may be formedin any desirable or convenient form, but at present'I prefer that shown in the accompanying drawings,in which each side frame has a deep passage therein, one side having a passage 4 for the lower sash 3 and the opposite side having a passage 5 for the upper sash 2. In these passages are contained the devices for holding the sashes in the desired positions and for keeping the said sashes tight. On referring to Fig. l, the preferable construction of, these devices will be more clearly seen, and as there shown they comprise on each side a closing-strip (l, a back strip 8, links 9, connecting said strips 6 and 8, and a spring 10, tending to cause the strip 8 to climb upward. This upward movement of the back strip 8 acting through the links 9 tends to force the closing-strip 6 against the sash, and if the spring be'made suliliciently stiff the sash will be held in any desired position. In order to regulate the tension of this spring so as to cause the closing-strip G to act on its respective sash with less friction, so that the sash may be movedmore easily, I form a rack 11 on the backstrip 8, and with this rack engages a pinion 12, fast on and moving with a shaft 13. To the outer end of this shaft is secured a hand -Wheel 14, by which the spindle may be turned, and a locknut 15, by which said spindle may be held in any desired position. By turning this handwheel in one direction the back strip 8 may be moved so as to act on the closing-strip 6 through the pivoted links 9, and thus relieve part of the pressure on the sash. The sash may now be moved with great ease, and when the operator raises or lowers it to the desired place the hand-wheel may be released and the spring 10 will elevate the back strip 8, which in turn will act on the closing-strip 6 through the links 9 and cause said closing-strip to bind the sash and hold it in the proper position. If the spring 10 should become `weakened or should fail to work,because of breakage or any other reason,the hand-wheel 14 may be turned in the opposite direction, so as to pull the back strip upward, and the sash can then be locked, even with an ineii'ective spring; but in this event the lock-nut 15 must be used to prevent the back strip 8 from moving, and thus releasing the sash.

From an inspection of my drawings it will be seen that the closing-strips 6 are beveled, so that their largest dimension isat the center line, where the two sashes move on each other, and the sashes are correspondingly beveled, as clearly shown in the drawings. (See particularly Figs. 3 and 6.) The object of this construction is to insure tight sashes, as the springs 10, acting on the beveled closing-strips 6, cause said strips to press the sashes laterally against the walls of the recesses in which they slide. For instance, in Fig. 3, 16 indicates the beveled edge of the closing-strip 6, and this beveled edge acting on the corresponding beveled edge of the sash 3 causes said sash to move laterally in the direction of the arrow, and thus prevent I wind or dust from entering between the side of the frame and the sash. It will thus be seen that there is a coaction between the spring-pressed closing-strip and the beveled sash. It will also be observed that the two sashes are beveled in opposite directions, as seen in said Fig. 3, and this construction causes the springs to act on the closing-strips and move the sashes laterally in opposite directions, so as to make a tight closure all around the window-frame. lf the sashes t a little loosely, this will tend to allow leakage between the meeting-rails, and to prevent this I form horizontal lianges 17 on the meeting-rails 18, one of which iiangcs projects over the other when the sashes are closed, and thus prevents the objectionable leakage. This construction is practicable with other forms of spring-operated closing-strips, as Will be seen in Fig. 6, in which 19 indicates the closing-strip, and 20 the spring, which has its rear end seated in the window-frame.

It will be noticed that my drawings do not show the usual beading-strips to allow the sashes to be removed, and as a substitute for these strips I provide detachable strips 21 and 22 at the rear of the lower half of the passage or groove for the upper sash. These strips are shown in detail in Fig. 4c and in section in Figs. 2, 3, and 6. The upper of these strips 21 is beveled on bot-h of its ends, so that it is wedged in position and held by the strip 22, which is secured by the screws 23. With this construction when it is desired t0 remove the sashes the screws 23 are removed from the lower strip 22, when the strips 21 and 22 may be easily pulled out of place. This leaves an opening, and the upper sash is then allowed to descend until it comes down opposite said opening, when it may be pushed laterally thereinto. This will cause the stile on the opposite side of the sash to be free from the walls of its passage, as clearly shown in Fig. 5, when the sash can be moved in an opposite direction, and thus be entirely removed from the frame. It will be obvious that it will take only a reversal'of vthis operation to replace the sash. l

From the foregoing and the accompanying drawings it will be seen that I have invented a window of a very simple construction which dispenses with the usual pulleys, cords, and weights and which is specially adapted for use in cars, although applicable to any other use and is, in fact, shown in a window adapted for two sashes. It is obvious that many changes may be made in its construction, and I intend the following claims to cover all such variations and modifications as natually fall within the scope of my invention.

What I claim as new is- 1. A vwindow-frame having an opening or recess in one of its sides, a sliding sash, closing and back strips, spring-actuated means for pressing said closing-strip against said sash, and means for regulating said pressure, said regulating means being situated between said strips, whereby it holds said back strip in position without the aid of guiding-pins, substantially as described.

2. A window-frame having an opening or recess in one of its sides, a sliding sash, closing and back strips, spring-actuated means for pressing said closing-strip against said sash, and means for regulating said pressure comprising a rack and pinion, said rack and pinion being situated between said strips,

whereby said back strip is held in position without the aid of guiding-pins, substantially as described.-

3. A window-frame having a sliding sash with -a beveled edge, a closing-strip correspondingly beveled, means for pressing said strip against said sash comprising a back strip and a spring coacting therewith, and means for regulating the pressure on said closing-strip, said means being situated between said closing and back strips, substantially as described.

4:. A window-frame having a sliding sash with a beveled edge, a closing-strip correspondingly beveled, means for pressing said strip against said sash comprising a back strip and a spring coacting therewith, and means for regulating the pressure on said closingstrip comprising a rack and pinion, said rack and pinion being situated between said closing and back strips, substantially as described.

5. A window-frame having sashes sliding therein with their edges beveled in opposite IOO directions, a closing-strip for each of said sashes correspondingly beveled, means for pressing said strips against said sashes,where by the beveled edges cause said sashes to be pressed laterallyin opposite directions against the frame, substantially as described.

6. A window-frame having sashes sliding therein with their edges beveled in opposite directions, a closing-strip for each of said sasbes correspondingly beveled, means for pressing said'strips against; said sashes,where by the beveled edges canse said sashes to be pressed laterallyin opposite directions against,

` the frame, said means comprising back strips,

connections between said closing and back strips, and springs acting on said strips, substantially as described.

l In testimony whereof I affix my signature,

in the presence of two witnesses, this 18th 1o` I day of May, 1901.
